Detailed Photos
Gravimetric dosing unit
Using professional high-speed valve and reverse screw stirring technology and continuous weight lessness control technology,precise proportioning of raw materials andmixing can effectively avoid chromatic ab-erration and reduce labor.
Automatic air ring
The automatic air ring is a double air lip air ring composed of software and automatic contour control system, which is used to control the air volume of the upper and lower air lips to match the characteristics of the plastic polymer
Auto thickness control system
The system uses capacitive measurement technology to continuously measure thethickness during the film production pro-cess, mounted on a circular track, and con-nected to a 15" color

IBC
IBC can accelerate the cooling of the inner and outer sides of the film , improve the transparency, tensile strength and other physical properties,which is conducive to the stabilization of the film, reduce the film width error and improve the yieldtouch screen.

Horizontal rotary tower
In this method, the primary haul-off rollers and herringbone nippers make a 180-degree round-trip rotation, the film runs in a radius.This type of rotation allows the blown film die to remain stationary at all times, eliminating the "ripple" phenomenon by changing the film's running path to evenly distribute the thickness of the film bubble.
Automatic double winder
Automatic double winder is constitute with two stations that back to each other. Typically, it combines two winding stations with familiar machine functions into a complete set. With the various function, it produces both single layer and two-layers film. Besides.the machine is available to divide into two bodies for independent working according to the requirements of customer as well.
